I usually use my ipad on speaker for mumble app it ran smoothly pervious version but since I updated ios n the app it picks up echo now and the people on the other end says I sound robotic at times, never had these problems till I updated it

Follow up on my pervious comment. The echo issue the only way it goes away if I set my ipad volume to the lowest it can possibly be, on pervious app version it never echoed when the volume on ipad was all the way up. Also sometimes it gets a nasty screeching sound echoing even if my volume is at lowest which is a big problem no way of fixing even tried lower the volume in settings nada. ):
